This work presents a study of the polymer P3EHT (poly (3 - (20-ethyl) hexyl-thiophene)). Among the many features of the dynamics of polarons that could be studied further, we chose those related to changes in morphology. In addition, the verification of the model HJ can explain the photophysics of conjugated polymers, through the study of photoluminescence spectra.
The study of the dynamics of polarons through photoinduced absorption as a function of frequency allowed us to find the lifetimes of our sample with different morphologies.
Our results demonstrate that the morphology is not only to the study of polarons, but is also an essential feature to understand the new model HJ.
